In-House Developed Automated Fault Analysis with Multi-Collaboration of Asset Information System

The increasing complexity of transmission networks, along with the growing demand for higher reliability and operational efficiency, has driven the in-house development of automated fault diagnostic systems in TNB, known as Automated Fault Analysis (AFA). Initially designed and developed in 2021, AFA aimed to streamline accurate fault location determination, enable equipment performance assessment, and provide comprehensive diagnostics of fault events across high-voltage overhead lines (OHL) within the TNB Grid. By 2024, following user wide acceptance and its proven effectiveness, the system underwent further enhancements to introduce additional functionalities, improve system stability, and deliver a more user-friendly experience
